The machine of thek present invention may, in general, be considered to comprise a bed A, clamps B, groove cutting mechanism C, groove cutting mechanism D, notch cutting mechanism E, notch cutting mechanism F, boring mechanism Gr and rectangular opening cutting mechanism H. The clamps B are used to hold a pair of boards from which a pair of oppositely disposed jambs for window sash frames are to be made in parallel oppositely disposed fixed relation on the bed A., while the various mechanisms C, D, E, F, G and H may act on the boards to make the necessary cuts therein to produce the two sash frame jambs. ln describing the machine, it will be necessary to refer to the relative location of various parts on the machine and it is therefore desirable to name the sides and ends of the machine. The near side of the machine as viewed in Fig. 1, will he taken to be the front side of the machine, the far side of the machine as viewed in Fig. 1, will be taken to be the rear side of the machine, while the portion of the machine shown at the rightside of the sheet, as viewed in Fig. 1, will be taken to be the right or near end of the machine and the portion of the machine Y adjacent the left side of the sheet as shown in Fig. 1, will be taken to be the left or far end of the machine.

The floor upon which the machine is locatedV may be numbered 16. rThe bed A is supported on this floor and consists of a pair of long rails 17 mounted in horizontal parallel spaced relation on a number of longitudinally spaced supports 18 which may be of Eri-shape as shown, the said supports resting on the floor 1G and acting to hold the rails 17 in spaced relation above the floor. rlihe rails 17 are somewhat similar in formation to ordinry railroad rails and have at their lower edges wide outwardly projecting horizontal iianges and narrow inwardly projecting horizontal flanges. At their upper edges the rails have short outwardly projecting flanges and the inner and outer corners of the rails at their upper edges are bevelled at substantially 45 angles, as shown in the vertical sectional views taken through the machine. The rails 17 extend generally longitudinally of the machine and are connected intermediate the two ends of the machine by a pair of longitudinally spaced and transversely extending bars 19 and 20. There are three pair of clamps B for supporting the boards to be worked on by the machine, which boards may be designated J and K respectively. One pair of clamps B are disposed adjacent the far or left end of the machine, one pair of clamps B are disposed adjacent the central portion of the machine and one pair of clamps B are disposed adjacent the right or near end of the machine. rlhe central pair of clamps B are supported on the bar 19 and, as best shown in 3, include an upwardly extending standard 21 having a central upwardly projecting reetangular portion at its upper end to which oppositely disposed angles 22 are secured. The standard also has in outwardly disposed relation from the two angles 22 arms forming screw threaded hubs within which screws 23 work. rlhe screws 23 are provided with wheels 24 at their outer ends and have enlarged heads at their inner ends adapted to bear against the boards J and K respectively to tightly press the saine against the vertical flanges of the angles 22. Adjacent the forward end of the machine, and adjacent the rear end of the machine there are mounted on the rails 17 carriages 25 and 26 respectively, which carriages respectively support the two groove cutting mechanisms C and D and the carriage 25 supports the pair of clamps B adjacent the left end of the machine and the carriage 26 supports the pair of clamps B adjacent the right end of the machine. rlhe clamps B adjacent the left end of the machine include a standard 27 secured'to the carriage 25 and projecting upwardly therefrom and having spaced upwardly projecting arms to which brackets 28 are secured, which brackets project outwardly from the arms of the standard and form screw threaded hubs within which'screws 29 similar to the screws 23 worlr. The screws 29 carry wheels 30 at their outer ends and carry blocks 31 at their inner ends adapted to bear against the respective boards .l and K to clamp the boards tightly against the arms of the standard 27. A'standard 32 similar to the standard 27 is secured to the carriage 26 and projects upwardly therefrom and has similar upwardly projecting arms. Secured to standard 32v are brackets 33 forming screw threaded hubs spaced from the arms of the standard 32 and within which screws 84: work. The screws 3,4 carry wheels 35 at their outer ends and blocks 36 at their inner ends adapted to clamp against the respective boards J andl K to hold them tightly against the arms of the standard 32. The three sets of clamps B are so disposed that the boards J and K will be clamped in oppositely disposed parallel spaced relation well above the bed A of the machine in horizontal relation.

The groove cutting mechanisms C andv D will now be described. These two mechanisms C and D are very similar in constructionand in action there are some differences in the relative arrangement of the parts of the two mechanisms. rlhe carriage 25 is mounted for sliding movement on the rails 17 andr is adapted to he heldin a desired spaced relation from the right end of the machine. For this purpose, a rack 37 is secured to the lower side of the upper outwardly projecting flange of the front rail 17 and the carriage 25 carries an arm 38 which projects downwardly at the forward side of the. carriage andhasmounted therein a. short shaft 39;towhieh issecured a.

pinion 46 meshing withthe rack 87. The

shaft 39 at its outer end is of polygonal forried thereby to be slid longitudinally of the rails 17. Bolted to the carriage 25 at the rear side thereof is a large upstanding guide 41 which is identically similar to a guide 42 bolted to the carriage 26 with the exception that the guide 41 will preferably be vertically disposed, while the guide 42 will preferably be inclined toward the left end of themachine relative to the vertical. To support the guide 42 in this inclined position, a wedge-shaped block 48 is provided which is disposed between the carriage 26 and the guide 42 and to which the guide 42 is bolted at its right end. lt may be here stated that the carriage 26 although capable of sliding movement on the rails 17, is preferably permanently fixed on the rails as by means of bolts 44 running` through the outwardly projecting flanges at the upper edges of the rails and fitting within screw threaded recesses in the carriage. The guides 41 and 42 are quite heavy in construction and, as best shown in Fig. 8, these guides are of general channel-shape and have triangular-shaped flanges projecting from their inner corners and received in under cut grooves in carriages 45 and 46 mounted respectively for sliding movement on 'the two guides 41 and 42. rllhe carriages`45 and 46 extend across the forward sides of the guides 41 and 42 and respectively carry electric motors 47 and 48 having armature shafts 49 and 50 respectively. rl`he two motors have brackets 51 and 52 secured thereto and carry suitable electrical switches 58 and 54 for opern ating the motors. Flexible cables 55 and 56 carrying electrical conductors run to the switches 58 and 54 respectively and from these switches to the respective motors 47 and 48. The armature shaft 49 projects from the motor 47 toward'the right end of the machine for short distance.j while the armature shaft 50 for motor 48 projects toward the left end of the machine for a short distance. The said projecting portions of each shaft 49 and 50 has mounted thereon a pair of spaced circular saws 57 and 58 respectively, and between each pair of saws there is mounted on the two shafts gullet saws 59 and 60. Collars 61 and 62 are carried by the two shafts 49 and 50 and nuts 63 and 64 screw threaded on the ends of the shafts 49 and 50, are used to tightly clamp the saws mounted on these shafts against the respective collars 61 and 62. The upper ends of the guides 41 and 42 are bifurcated and have journaled therein shafts 65 and 66 which'carry sheaves 67 and 68 over which cables 69 and 70 run. The cable 69 is secured tothe carriage 45 and runs downwardly from the sheave 67 and has secured thereto a counter balancing weight 71, while similarly the cable 69 is secured at one end to the carriage 46 and runs downwardly from the sheave 68 and has secured to its other end a counter balancing weight 7 2. The weights 71 and 72 are used to counter balance the weight of the carriages 45 and 46 and the parts carried thereby, so as to permit the carriages tobe raised and lowered readilyl on the guides 41 and 42. Casings 78 and 74 are secured to the rear portions of the carriages 25 and 26 and the weights 71 and 7 2 ride upwardly and downwardly against the outer sides of these casings and are prevented from coming in contact with other mechanism that will be later described. The two guides 41 and 42 are provided with large rectangular openings 41a and 42a respectively, and the two carriages 45 and 46 carry on their rear sides brackets 75 and 7 6, which project through the openings 41a and 42a respectively and are offset rearwardly from the rear sides of the carriages.

`Mounted on the floor 16 is an electric motor 77 controlled by a switch 78 mounted on a bracket 79 carried at the right end of the ferward rail 17 asbest shewnin Fig 1. flexible cable 80 carrying electrical conductors runs from a source of electricity to the switch 78 and thence to the motor 77. Mounted on the lower'outer wide flange of the front rail 17, are two or more brackets f 8l carrying grooved rollers on which a rod 82 travels.

rlhe rod 82 projects beyond the right end of the machine and carries a pin 88 at its right end which when the rod is slid to the right,

will close the switch 7 8. A spring 84 is secured at one end to the rod 82 andl at its other end to the front rail 17 and this spring acts to normally slide the rod 82 to the left to bring thel pinr83 out of contact with the switch 78 and thereby break the electric circuit to the motor 7 7; The rod 82 is equipped with a handle 85.V A pair of brackets 86 are bolted to the outer flanges of the two rails to extend below the same, as best shown in F ig. 5, and these brackets have portions extending transversely of the rails and forming bearings for a long shaft 87 extending to a point adjacent the motor 77. rlhe shaft for the motor 77 carries a pinion 88 which meshes with a large gear 89 mounted on the right end of the shaft 87. The brackets 86 have p rtions forming bearinvs for two transverse shafts 90 whichv project beyond the rear rail 17 and extend forwardly to points adfa ent the shaft 87. Each shaft 88 carries at its crward end a ring gear 91. lt will be noted that one of the brackets 86 is located near the right end of the machine below the groove cutting mechanism D, while the other of the brackets 86 is located adjacent the left end kof the machine and below the groove cutting mechanism C. The shaft 87 adjacent its right end carries a bevelled gear 92 which meshes with the ring gear on the shaft 90 adjacent the right end of the machine and the shaft 87 also carries acent its left end a bevelled gear 93 which meshes with the ring gear 91 carried by the shaft 90 adjacent the left end of the machine. The bevelled gear 92 may be fixed to the shaft 87 but the gear 93 will be mounted on the shaft 8? for rotation therewith, but for sliding movement relative to the shaft. For this purpose the shaft 87 is provided with a lone" slot 87a and the gear 93 carries a cross pin .sil

or hey which travels within slot 87a. The bevelled gear 93 is slidably mounted on the shaft 8'? in order that the'lcft hand braclret 86 may be slid to different positions and secured on the rail 17 so that the spacing of the left hand bracket 8G from the right end of the machine may be varied as the spacing of the groove cutting mechanism C from the right end of the machine is varied. @ranks 94 are secured to the rear ends of the shafts 90 and these cranks are connected by crank pins 95 to pitmen 96 connected respectively by crank pins 97 to the brackets 75. t will be seen as 'the two shafts 90 are rotated through 180O to swing the cranks 9a from a vertical position above the shaft to a vcrtical position below the shaft, the two carriages l5 and 16 i i be lowered from an upwardly raised position with the saws 57 and 58-60 abovethe boards J and 'l to a position where the said jaws extend below the boards. Similarly, when the shafts 90 are rotated through 180O from a position where the cranks extend downwardly in vertical relation from the shafts to a position where they extend vertically above the shafts, the

carriages and i will be raised upwardly on the guides to raise the s aecifled saws from a position below the boards J and K to a position above the saine. he saws 57-59 and 58--G0 will be of such diameter and will be so positioned that these saws will move between the two boards l and l clamped in place by the three sets of clamps, so that the of thY saws will come in contact with bo-.n boards and the saws will thus eut grooves in the boards which extend generally transT versely to the boards. rlhe saws of the groove cutting mechanism C will cut grooves in the boards extending directly transversely across the ends of the boards, while the saws of the groove cutting mechanism D due to the inclination of the guide 1-2 will cut grooves which extend diagonally across the boards. lt is desirable when the motor '277 is set in operation by sliding the rod 8; to the right, that the motor remain in operation until the two shafts 90 have been rotated through 180o and then that the motor be put ont or operation. ln order that this may be accomplished, the rod 82 is angularly bent transversely of the machine at its right end and then downwardly bent best shown in ll ig. 5, and provided at its lower end with a bend extending longitudinally of the machine and towards the left end of the same to form a Leriaeoe dog 92a, as best shown in Fig. 9. A ratchet 98 is mounted on the shaft 90 adjacent the right end of the machine and this ratchet is provided with angular teethy at diametrical points as shown in Fig. 9. As the motor 77 is in operation,by sliding the rod 82 to tlie right, the dog 82a formed by the rod will 'ie slid out of engagement with one tooth of tie ratchet 98 and the dog 82a will then ride n one circumferential portion of the ratchet 8 until the dog 82a is carried into the notch tire opposite side of the ratchet, whereupon l e d g 82a will engage the other shoulder of he ratchet and the spring 811 will cause the od to slide to the left and thereby open the switch 78 to stop the motor 77. lt will, accordingly, be seen that whenever the rod 82 is slid to the right, the motor 77 will be actuated to swing the shafts 90 through 180o and to thereby cause both carriages 4:5 and i6 'to be either lowered from an extreme upwardly raised position to an extreme lower position on the guides l1 and 42 or to cause tie l carriages to be raised from their eX- treme lower positions to their eXtreme raised positions.

The notch cutting mechanism E is constructed to operate in synchronism with the groove cutting mechanism C, while the notch cutting mechanism F is constructed to open ate .in synchronism with the groove cutting mechanism l). rthe two carriages and 26 carry on their upper faces transversely eX- tending ribs 25a and 26a respectively, which are oppositely diagonally inclined to form guideways for carriages 99 and 100 respectively mounted thereon. The two carriages 99 and 100 have motors 101 and 102 respectively bolted thereon and the shafts for these motors carry pulleys 103 and 104i respectively over which belts 105 and 106 run. 'lhe belts 105 and 100 also run over pulleys 107 and 108 respectively carried by shafts 109 and 110 journaled in bearings 111 and 112 mounted on the carriages 99 and 190 respectively adjacent their rear sides. Secured to the right end of the shaft 109 is a rack saw 113, while secured to the left end of the shaft 110 is a similar rack saw 114, and these rack saws are i'nounted at such a level as to engage the respective ends of the boards J and K at their lower edges when the carriages 99 and 100 are slid transversely of the bed A. The motors 101 and 102 have electric switches 115 and 116 re `pectively mounted thereon which control the supply of electri-cityto the motors armored cables 117 and 118 carrying eleci cal conductors respectively run from a source of electricity to the switches 115 and 119 and thence to the two motors 101 and 102. livoted to the upper end of the right side of the guido l1 is an arm 119 of angular shape in cross section and a similar arm 120 is pivoted to the upper end of the left side of the guise d2. rlhe two arms 119 and 120 are prefif) C,

" tered by these saws.

erably bent' as best shown in Fig. 5 and have respectively pivoted to their lower ends pitman rods 121 and 122 which rods are pivotally connected respectively at their forward ends to the rear ends of the carriages 99 and 100. The right side of the carriage 45 has an arm 123 secured thereto which projects rearwardly from the carriage beyond the guide 41 and this arm is angularly bent at its rear end to project over the arm 119. The arm 123 carries a pair of spaced roller shafts 124 on which rollers 125` are journalled and one flange of the arm 119 worlrs between the two rollers 125. A similar arm 126 is carried at the left side of the carriage 46 and projects rearwardly beyond the guide 42 and this arm carries short shafts 127 on which rollers 128 are journaled. One flange of the arm 120 works between the two rollers 128. With'this construction, it will be seen that as the .two carriages 45 and 46 move downwardly on he guides 41 and 42, the arms 123 and 126 will be moved downwardly with the carriages and t ie rollers 125 and 127 respectively acting on the arms 119 and 120, will swing the lower ends of these arms 119 and 120 forwardly to move the pitman rods 121 and 122 forwardly and thus slide the two carriages 99 and 100 across the carriages and 26 from adjacent the rear side thereof to adjacent the front side thereof. As this is done, the two rack saws 113 and 114 will be moved across the ends of the lower edges of the boards to cause notches to be cut in the same. The action of the pitman rods 121 and 122 is such that before the carriages and 46 arelowered to such a point as to bring the Saws 57 29 and 58-6O below the lower edges of the boards, the carriages 99 and 100 will be swung so far forwardly that f the saws operated from the motors 47 and 48 cannot come in contact with the rack saws 113 and 114 and the rack saws 112 and 114 will be completely out of the way of movement of the carriages 45 and 46 and the parts carried thereby. lt will be understood that when the carriages 45 and 46 are raised, the carriages 99 and 100 will be slid rearwardly to again'cause the rack saws 113 and 114 to traverse the lower edges of the boards K and J adjacent the ends thereof. If desired, hoods such as the hood 129 may be applied to the carriages 45 and 46 to partially encompass saws operated from the motors 47 and 48 to prevent saw dust and shavings being scat- The hood 129 illustrated cut away on its edges at its right side and the left si of the hood forms a stop or abutment fer the left ends of the boards .l and K as they are inserted in place to be clamped by the clamps B. The casings 73 and 74 prevent the counterbalancing weights 71 and 72 from interfering with the action of the cranks 94. f j

Boring mechanism G will now be described and this mechanism is best illustrated in Figs.

1,2, 6 andv7. Mounted for longitudinal sliding movement on the two rails 17 to the right of the mechanisms C and E is a carriage 130. This carriage has transverse ribs 130@ eX- tending upwardly at inclined and opposite directions formed on its upper surface which form guides for a carriage 131 which is mounted for sliding movement transversely of the hed and of the carriage 130. An electric motor 132 is secured to the carriage 131 adjacent the rear side thereof, and forward f ef this motor is a gear casing 133 mounted on the carriage 131 and projectingiupwardly therefrom between the positions of the boards J and K when clamped in place on the machine. The armature shaft 134 of the electric motor 132 projects forwardly into this gear casing 133 and the forwardend of the shaft is journaled in this gear casing. A shaft 135 is -journaled in the gear casing 133 above the motor shaft 134 and a large pinion 136 mounted on the motor shaft 134vwithin the' gear casing 133, drives a gear 137 mounted on he shaft 135. A pair of vertically alined and vertically spaced shafts 138 are journaled in the gear casing 133 adjacent its upper end and these shafts carry within the gear casing gears 139 and 140, the gear 139 beingA driven from the gear 137 and the gear 140 being driven from the gear 139. The shafts 138 project beyond the front and rear sides of the gearcasing 133 and carry chucks 141 at -theirends which are used to releasably hold A pair of clamps 145 are releasably secured v to the lower wide outer flanges of the rails 17 and these clamps form bearings which project below the rails for reception of a shaft 146 extending transversely below the bed and having a lever 147 secured to its forward end.4 The carriage 130 has a pair of spaced lugs 143 projecting downwardly therefrom between the rails 17 and an arm 149 secured to the shaft 146 extends upwardly and projects between the two lugs 148. By swinging the `lever 147, it will be seen that the carriage 130 and parts carried thereby may be slid longitudinally of the bed A. The earriage 130 has a transverse slot formed in its central portionl and the carriage 131 has transversely spaced lugs 150 on its under surface which project into the transverse slot of the carriage 130. A shaft 151 extending longitudinally of the bed is journaled in ears 152v projecting` downwardly from the carriage and t-his shaft 151 carries an arm 153 which projects upwardly between the two lugs 150. An angularly bent lever 154 is secured to one end of the shaft 151 and projects forwardly beyond the forward side of the machine. An arcuate plate 155 is bolted to the carriage 130 adjacent the formed edge thereof and this plate is provided with a notch within which a dog 156 pivoted to the lever` 154 is adapted to fit. A link 157 connects the dog 156 to a handle 158 of the bell crank lever type which handle is pivoted to the lever 154 adjacent its outer end and is pressed outwardly by a spring 159 to normally hold the dog 156 into engagement with the arcuate plate 155. 1t will be seen that as the outer end of the lever 154 is swung upwardly and downwardly, the carriage 131 may be slid forwardly and rearwardly transversely of the carriage 130 and bed A. l/Vhen the dog 156 is in engagement with the notch on the plate 155, the carriage 131 will be so disposed that the gear casing 133 is centrally located relative to the boards J and K.

Although various type of stops may be used for limiting the sliding movement of both the carriage 130and the carriage 131, there are illustrated in the drawings as best shown in Figs. 6 and 7, stops for this purpose. A bar 160 shaped as'shown in Fig. 6, extends generally longitudinally of the machine and is secured at its left end to the standard 27 for the left pair of clamps B. This bar projects below the carriage 130 and is upwardly bent at its right end and carries therein a scr w 161 adjustably locked in the bar-166 by a loclf: nut 162 and this screw 161 i's-adapted to strike the right end of the carriage 130 to limitthe extreme longitudinal sliding` movement of the carriage 136 toward the right end of the bed A. A. screw 163 is mounted in the left end of the carriage 131 and this screw is adjustably locked in place on the carriage by means of a loch nut 164. The head of the screw 163 is adapted to contact the standard 27 to limit the extreme longitudinal sliding movement of the carriage 136 toward the left of the bed A. The carriage 131 can be freely slid forwardly and rearwardly on the carriage 130, when the carriage'130 is located in a general central position between the two extreme longitudinal stops. rlhere is a pin 165 secured to the left end ofthe carriage 131 and projecting downwardly therefrom and this pin is adapted to ride between a pair of longitudinally spaced blocks V166 carriedby the bar 160 after the drills 142 have been brought into contact with the hoardl and moved therein for some little distance. lhen the carriage 131 is positioned so 'that the pin 165 extends between the two bloclrs 166, longitudinal movement of the'carriage 130 on the bedV is limited in both directions by contact of the pin 165 with the blocks 166. rl`he pin 165 and the blocks 166 are located relative to each other so that the drills 142 may bore for some distance into the board K and the longitudinal movement of the carriage 136 will be only limited by engagement of the right end of the carriage with the stop 161 and by the engagement of the stop 163 with the standard 27. VThe blocks 166 will prevent sliding` movement of the carriage 131 rearwardly beyond a point where the pin 165 contacts the forward surfaces of the blocks 166 unless the pin 165 is located midway between the two blocks 166. he bloclrs 166 will preferably be mounted on the bar166 for sliding adjustment. Another pin 167 issecured to the carriage 131 adjacent the rear end thereof and projects upwardly therefrom. An angular bar 163 is secured to the standard 27 adjacent its rear side and this bracket carries spaced blocks 169 which cooperate with the pin 167 to limit longitudinal sliding movement ofthe carriage 130 within certain distances when the carriage 131 has been slid forwardly on the carriage 136 to bring the two forward drills 142 into engagei'nent with the board J. 'lhe carriage 131 may be freely slid forwardly on the carriage 130 and the longitudinal sliding movement ofthe carriage 130 will not be limited by engagement between the pin 167 and the blocks 169 until the drills 142 have moved into the board el" for some little distance, i. e. the carriage 130 may be longitudinally slid until the stop 161 engages the right end of the carriage 130 and `until the stop 163 engages the standard 27, while the forward drills 142 are boring for a short distance into the board J. `When, however, the pin 167 is located centrally relative to the two blocks 169, the carriage 131 may be transversely slid on the carriage 130 to permit the drills 142 to be carried entirely through the board d. By this construction, it willv be seen that elongated shouldered openings may be cut through the two boards by the boring mechanism G.

rlhe rectangular opening` cutting mechanism H will now be described. rlllhis mechanism is best illustrated in Figs. 1, 3, 4, 10, 11, and 12. A longitudinally extending` drive shaft 17 0 is journaled in the two bars 19 and 20 connecting the rails 17. An electric motor 171 is mounted on the floor 16 and this motor has a motor shaft 172 on which a pulley 173 is mounted. A belt 174 runs over the pulley 173 and over a pulley 175 mounted on the right end of the shaft 170. rllhe motor 171 is controlled by a switch 176 which may be mounted on the carriage 26 and a flexible conduit 177 carrying electrical conductors runs from a suitable source of electricity to the switch 176 and thence to the motor 171. The shaft carries six eccontrics 178 thereon, three of which are fixed on the shaft adj acent the left end of the same in closely spaced relation and three of which are fixed to the shaft adjacent the right end of the same in closely spaced relation. A pair ofY central arms 179 have hubs at their lower ends mounted on two of the eccentrics 178 and one of the arms 179 is mounted on an eccentric 178 adjacent the left end of the shaft 170, and the other arm 179 is mounted on an eccentric 178 adjacent the right end of the shaft 170. The two arms 179 project upwardly above the shaft 170 and extend to a position between the two boards ,l and l as best shownin Fig. 8, so that the upper ends of the arms are at a level with certain portions of the boards J and lil when these boards are clamped in position. of mlim-shape and extend generally transverse to the shaft 170 and the machine. Received within grooves at the upper ends of the arms are short hatchet-like saw blades 180, each arm carrying` one blade with the teeth thereof facing` the board J and each arm carryii'ig` another blade having` its teeth facing the other board K. A pair of front arms 181 have hubs which are ournaled on two of the eccentrics 178 and one of the arms 181 is mountedron an eccentric 178 adjacent the left end of the shaft 170 and the other arm 181 is mounted on one of the eccentrics located adjacent the right end of the shaft 170. The arms 181 run upwardly to points adj acent but forwardly disposed from the position of th board J, when clamped in place and the upper ends of the arms 181 are groei/ed to receive d small hatchet-like saws 182 similar to the saws 180. A pair of arms 188, similar to Vth arms 181, have hubs at their lower ends ournaled on a pair of eccentrics 178, one arm 188 boing mounted on an eccentic 178 adjacent the left end of the shaft 17 0 and the other arm 188 being mounted -on one of the eccentrics adjacent the right end of the shaft 170. lhe arms 188 project upwardly to points rearwardly disposed from the position of the board l when clamped in place. rl`he upper ends of the arms 188 are grooved to receive ha.tcl'ieiike saws 18e which face the outer surfaces of the board K. The various hatchet-lilre saws 180, 182, and 184L are releasably clamped in the various arms' by means of crews 185. W ith the construction described, it will be seen that extend-.ing` upwardly from adjacent each end of the shaft 170, there are three arms and in each group'of arms there-is one central arm 17 9 and one side arm 181 and one side arm 188. The saws 182 and 181 of the ari s 181 and 188 are so positioned relative to the saws 180 of the arms 17 9 that the saws 182 and 1811 on arms 181 and188 adjacent the left end of the shaft 170, are disposed.

The upper ends of the arms 179arel of the saws 180 on the arm 179 mounted adjacent the right end of the shaft 170. The saws 182 and 18e on arms 181 and 188 adjacent the two ends of the shaft 170 are in transverse alinement.` lt will be seen that when the motor 171 is in operation, the arms 179, 181 and 188 and the saws carried thereby will be given an oscillatory movement. A. pair of logitudinally spaced brackets 186 are mounted on the inner side of the rear rail 17 and a pair of arms 187 are pivoted at medial points to these brackets 188. rEhe two arms 187 are interconnected by longitudinally eX- tending upper and lower rods 188 and 189 respectively, and links 190 are pivoted on the upper rods 188 and are also pivot-ally connected to the two central arms 17 9. The arms 187 and the rods 188 and 189 fo m what may be called a pivoted central frame for swinging the upper ends of the arms 17 9 transversely of the machine to throw saws 180 respectively into engagement with the boards J and K. Secured to the outer sides of the two rails 17 and projecting horizontally outwardly therefrom are spaced brackets 191 which are pivotally connected to the lower ends of arms 192 interconnected by lower and upper bars 198 and 1941 respectively, and forming what may be called side frames. The arms 192 at each side of the machine are interconnected at their upper ends by longitudinally extending rods 195 on which are pivoted links 198, which are also pivotally secured at their inner ends to theV arms 181 and 188 respectively adjacent thereto. The arms 192 forming portions of the frame just described at the front side of the machine, are additionally interconnected by a rod 197. The arms 192 forming portions of the frame at the rear side of the machine, are additionally interconnected by the rod 198 and short inwardly projecting arms 199 secured to the arms 192 at the rear side of the frame are interconnected by a horizontal rod 200. lt will be seen that the arms 181 and 188 can be inwardly swung in a transverse direction to carry the saws 182 and 184e mounted thereon into engagement with the boards J and K respectively, as the side frames just described are swung); inwardly. rlhe side frames are normally held in outwardly swung relation against stops 281 secured to the rails 17 by means of stiff springs 201 which are secured to the outer edges of the wide flanges of the rails 17 andv project upwardly therefrom and bear against th bars 198. Accordingly, the saws 182 and 184: will normally be held out of engagement with the boards J and K in outwardly disposed relation therefrom.

hdjacent the various arms 179, 181 and 188,

is mounted on the rails 17 a longitudinally sliding` carriage 202 consisting merely of a pair of transversely spaced horizontal having grooves in their under surfaces receiving the upper edges of the rails 17. rl`he two bars forming the carriage 202 carry diagonal transverse ri s ou their pper surfaces 'e direct projecting i s and forining i fsversely sliding carriage intercoi'inecis the two bars formi o the ca 202, so that these bars A13 .J will slide together. The carriage 203 includes a pair of horizmntal and longitudinally extending bars 2036i grooved to receive the ribs on the bars of the Carriage 202 and re ting on these bars, and a central cross bar 2035 intercormects the two bars 203e. The central cross bar 2035 notched at its lower to permit of transverse sliding movenient of the carriage 203 respective to the carriage 202. in arm 204 is secured to the cross bar 2035 anc this arm is forked at its lower end to receive the rod 189 of the inner frame for swinging arms 17 9. Also secured to the top .f lrface of the bar 203?) are angular bars 205 and 206 respectively, one of which disposed outwardly from the rod 197 of the outer frame at the front side of the machine and the other of which is disposed outwardly from the rod 200 of 'he outer fra at the rear side of the machine. l'lilhen the carriage 203 is disposed in central relation that the arms 170 are centrally disposed between the two boards J and l, the two angular bars 205 and 20ol will be disposed in oppositely spaced relation respectively from the rods 197 and 200, so that tl ey will not contact these rods. Mounted on the bar 2032 of carriage 203 and projecting upwardly therefrom between the position of the two boards pl and l, is standard 207 and this standard. .iay be forked at its upper end as shown. An electric motor 208 is secured to the forked portion of the standard 207 above the position of the boards J and K and this motor is controlled by an electric switch 209 to which a flexible conduit 210 carrying electrical conductors extend. The motor 208 has a motor shaft 211 projecting vertically downwardly therefrom and a pair of horizontal and vertically spaced circular saws 212 are mounted on this motor shaft 211. Collars 213 mounted on the shaft 211 bear against the upper side of the upper saw 21 and against the lower side of the lower saw 212 respectively, and a. spacing collar 214 is interposed between the two circular saws. Vllhe lower end of the shaft 211 is screw threaded and a jamb nut 215 is mounted on 'et 211 and removably the lower end of the shalt secures the saws 212 and collars 213 and 211i in tightly assembled relation.

il. racliy 2 is bolted or otherwise secured to the re l 17 below the upper outwardly enten ng flange thereof and a bracket 217 secured to the under sido of the rear bar of the carriage 202 and projects downwardly therefrom to form a hub within which a shaft 2 is jonrnaled for rotary and sliding movement. lhe shaft 218 carries a Pinie-11219 at its inner end engaging with the rack 216 and the shaft is equipped with a wheel 220 at its outer end. 11 plate 210s is secured the rack 210 and projects downwardly therefrom to retain the pinion 219 in engagement with raclr 216 and to prevent outward sliding movement of shaft 218. ly rotation of the wheel 220, the carriage 202 together with the carriage 203 and parte carried thereby may be slid longitudinally of the rail 17. Mounted n the rear bar of the carriage 202 and projecting upwardly therefrom is an angular bracket 221 which forms an apertured hub within which a shaft 222 is journaled. rlhe shaft 222 carries a wheel 223 at its outer end and a collar 22d inwardly from the hub of bracket 221. inwardly from the collar 22d the shaft 222 is screw threaded and works through a nut 225 mounted on the rear bar 2030i of carriage 203. By rotation of the wheel 223, it will be seen that the carriage 203 together with the parts carried thereby may be slid transversely of the bed. Vfransverse sliding movement of the carriage 203 is limited by means of stops 226 extending' in vertical relation from the rear and front edges of the carriage 202 and having screws 227 mounted therein adapted to engage the front and rear sides of the transversely sliding carriage 203. The screws 227 are adjustable in thestops226 and are locked in place by means ofjamb nuts 228. Londitudinal sliding inovement of the carriage 202 is limited by means of two stops 229 mounted on the front rail 17 in spaced relation from the central position of the ends of the bars 203e of the carriage 203. `When the carriage 2036 is centrally disposed relative to its limits of transverse movement, longitudinal sliding movement of the carriage 202 and, accordingly, of the carrie-ge 203 is limited in both directions by contact of the ends of the stops 229 with the ends of the front bar 203e. Carried by the stops 229 are screws 230 which are adapted to contact the ends of the carriage 202 to limit the extreme sliding movement of this carriage when the carriage 203 has been transversely slid to such a point that the ends of the stops 229 will be disposed either at one side of the front bar 2030J or at the other side thereof. Screws 230 are adjustably locked in place by jamb nuts 230e.

ln Figs. 13, 14, and 15, there is illustrated a window frame jamb K formed by use of the present machine. rlhis jamb has at its left end a groove c extending transversely across the inner face of the jamb and adapted to be cut by the groove cutting mechanism C of the present machine. At its right end, the jamb l has a groove CZ cut therein and extending generally transversely of the jamb in the inner face of the amb, but inclined toward the left end of the from the lower edge of the jamb as shown in Fig. 13 to the upper edge of the jamb, the groove al is adapted to i ceive shouldersIV formed at the inner ends o openings are adapted to be cut by the boring mechanism Gr. lt willV be noted that these pulley receiving openings are shouldered at their ends on the inner face of the j amb K. Adjacent the right end ofthe jamb K there is found a rectangular opening 7L forrreceiving the sash weights of a window frame and this opening is adapted to be cut by the rectangular opening cutting mechanism H. It will Vbe noted that the Vends'of this rectangular opening 7L areshouldered inwardly from the inner face of the jamb K. The machine of the present invention is not only adapted to form the grooves c and d, notches c and 7, pulley receiving openings g and rectangular sash weight receiving openings h' in a jamb K which will be used as the left jamb for a sash frame, but the machine of the. present invention is also adapted to cut similar grooves,notches and openings in a right hand jamb el, which will match with thej amb K to form the right hand j amb for a sash frame Vin which the `jambs may be assembled. The

grooves c ofthe jambs are adapted to receive the tenons formed at the ends of aheader in the sash frame, while the notches e ar-e adapted to receive projectingl shoulders at the edge lof the inner ends of the header. rlhe grooves CZ are adapted to receive tenons formed at the ends of the sill of the sash frame, while the notches 7 are adapted to rejambs of window sash frames will be placed near the machine. rrllhe motors 47, 48, 101,

. 102, 132, 171 and 208 will then be set in operation to cause the circular and gullet saws 57-59, 58-60, the rack saws 118-4114, and the circular saws 121 to be rapidly rotated and to cause the drills 142 to be rapidly rotated and the hatchet-lilesaws 180,y 182 and 184 to be rapidly oscillated.l rlhe machine will preferably be controlled` by two operators, one of whom will stand at the front side of the machine and will control the sliding rod 82 and the levers 147 and 154 and the other of whom will stand at the rear side of the machine Vand will control the two `of vthe machine.

wheels 220 and 223. A pair of boards J and K will be clamped in place in oppositely disy posed spaced parallel relation by the varous clamps B.r The'operator at the front side of the machine will then grasp the handle 85 and slide the rod 82 against the tension of the spring 84 to the right, thereby closing the switch 78 and causing the motor` 77 to be set in operation. The motor 77 will then operate until the gears 91 and shafts 90 have been carried through 180, whereupon the motor 77 will be shut off, as has been previously described. As the shafts 90 are rotated through 180, the carriages 45 and 46 will be either carried downwardly through their-length of movement, or will be carried upwardly through their length of move-v ment and the saws 57--59 and the vsaws 58-60 will be carried into engagement 'with vand across the ends of the two boards J and K to cause the grooves yc and CZ to be made in the boards. vAt the same time that the carriages 45 and 46 are slid upwardly or downwardly, the carriages 99 yand 100 will be slid transversely of the carriages 25 and 26 to cause the rack saws 113 and114 to be engaged with and carriedl across the ends of the lower edges of the boards J and K to cut the notches f then be swung upwardly to slide the carriage 131 on the carriage 130 towards the rear side y The drills 142 extending towards the rear side of the machine will then be brought into engagement with the board K and `the lever 147 will then be swung first toward oneend ofthe machine, then toward the other end of the same to cause the carriage 130 to ride longitudinally back and forth on the rails 17. The lever 154 will be maintained in continued upwardly swung relation to maintain the drills 142 facing toward the rear side of the machine in engagement with the board K. Considering` that the drills 142 are first engaged with the board K when'the lever 147 is swung as far tothe right end of the machine as possible, the right end of the carriage 180 will engage the stop screw 161 and the drills cany only be carried into the board K for a short distance or until the pin 165 engages the front face of one of the blocks 166. As the lever 147is swung toward the left end of themachine, the drills sok carried over the left front corncrof the right hand block 165, the drills 142 will be carried further into the board K to form the central openings or slots of the openings g, whereupon the pin 165 will strike the right end surface of the left hand block 166. The lever 154 will then be swung downwardly slightly to carry the pin 165 around the right forward corner of the block 166, whereupon as cn g Cil

the lever 147 continues to be swung to the left, the drills 142 will cut the should-ers at the left end of the opening g in the board K. Preferably the lever 147 will also be swung toward the right end of the machine, so that all portions ofthe openings f/ may be smoothly cut. The cutting of the openings g in the board K is a continuous operation and takes but a few seconds. `After the openings g of the board K are cut, the lever 154 is swung downwardly, whereupon the drills 142 projecting toward the forward side of the inach-ine will be brought linto engagement with the board J and the openings g in this board may be cut in similar manner, the pin 167 acting with the blocks 169 in exactly the same manner as did the-pin 165 with the blocks 166'in the'previous operation. 'Gf course, the-screws 161 will engage the right side of the carriage 130 and the heads of the screws 163 will engage the standard 27 to limit the eXtreme length of shoulder cuts of the openings g. As the screws 161 and 163 may be adjusted, it will be seen that the length of shou-ldered cuts may be varied. The spacing between the two blocks 166 and the spacing between the two'blocks 169 willdetermine the length of cut of the central slots of the openings g and as the blocks 166 may be held in different positions on the bar 160, and as the blocks 169 may be held in different positionsv on the bar 168, it will be seen that the length of the central slots of the openings g may be varied. After the openings g have been cut in both boards J and K, the boring mechanism G will be slid to central position between the two boards ll andK by operation of the lever 154 and the handle lever 158 will be released to permit the dog 156 to again engage with the notch of the arcuate plate 155.

At the same `time that the operator at the front side of the machine is causing the mechanisms C, D, E, F and G to out the grooves c, CZ, the notches c, f, and the pulley receiving openings g in the twoboards J 'and K, the operatorat the rear side of the machine will cause the rectangular opening cutting mechanism H to cut the rectangular openings 7L in the two boards. The original position of the hatchet-like saws 180, 182 and 184 and the circular saws 212 relative to the boards J and K will be as shown in full lines Fig. 10, as the two boards il and K are clamped in place by the clamps B. The operator at the rear side of the machine after the boards are clamped in position, will first rotate the wheel 232 as in a counter clockwise direction looking towards the wheel as the operator faces the same. This will cause the screw portion of the shaft 222 to be threaded outwardly from the nut 225 tothereby `cause the carriage 203 to slide on the carriage 202 toward the front side of the machine As this is done, the forked arm 204'whicli engages the vrod 189, will swing the inner frame formed .by the arms 187 and rods 188 and 189 to carry the upper end of the frame toward the rear side of the machine and thus to cause the links 190 to swingthe central arms 17 9 toward the board K and then cause the hatchet saw 214 projecting toward the board K to be carried into engagement vwith the same to make the extreme end cuts in the board K extending into the board from the inner face thereof. Also as the carriage 203 is slid toward the front'side of the machine on the carriage 202, the angular bar 206 will engage the rod 200 to 'swing the upper end of the outer frame at the rear side of the machine formed by the arms 192, bars 193 and 194 and rods 195 and 198 and 200 inwardly to thereby cause the links 196 pivotally secured'to the outer arms 183 to move inwardly toward the outer side of the board K. rllhe hatchet-like saws 184 will then be carried into engagement with the outer side of the board K and as ythese saws are oscillating they will quicklymake the end cuts of the rectangular opening 71, in the board K which end cuts eX- tendV inwardly into the board from the outer face thereof. As the carriage 203 moves toward the forward-side of the machine,and at the same time that the rearwardly projecting saws of the central arms 179 are carried into engagement with the inner face of the board K and the saws 184of the outer arms 183 are carried into engagement with the outer face ofthe board K, the circular saws 212`will be brought into engagement with the innerface of the board J. The wheel 220 will be rotated to cause the gear 219 to engage the rack 216 and thereby slide the carriage 202 together with the carriage 203, standard 207, motor 208 and circular saws 212 longitudinally of the bed A and thereby cause the circular saws 212 to make the longitudinal extending side cuts of the opening 7L in the board J. The relative positions ofthe various saws 180, 182, 183 Vand 212 during this first cutting action is illustrated in F-ig. 11, the circular saws 212 being shown in their eXtreme right hand position in full lines and eXtreme left hand position in dotted lines. It will be observed that when the saws 180 of the central arms 179 are in engagement with the board K, it is possible to move the circular saws 212 through their eXtreme movement without causing the circular saws to come into engagement with the forwardly facing saws 180 on the central arms 179. The stop screws 230 will limit the sliding movement of the carriage 202 longitudinally of the rails 17 by contact with the ends of the carriage 202 when the various hatchet-like saws are in the position illustrated in Fig. 11. In this position the stops r229 cannot engage the bars 203e of the trans-V i engagement with one of the boards J or K.

In other words, the fro-nt bar 203e of the carriagev 203 can' only move beyond the stops 229 in either transverse direction to bring the same into engagement with the stop screws 230 when the central arms 179 and the saws .180 carried thereby` are so positioned that the circular saws 212 cannot Vengage the arms 179 or the saws 180 carried thereby. The stops 229 are, therefore, provided to make the machine fool proof. VAfter the longitudinalside cuts for the rectangular opening 8 have been made in the board J, the wheel 220 will be rotated until the carriage 203 is located in the central position rela* tiveto the stops 229, whereupon the wheel 223 may be rotated in a clockwise direction to thread the screw portion of :the shaft 222 into the nut 225 and thereby slide the carriage 203 toward the rear side of, the machine on the carriage 202. As this is done,

the angular bars 206 are disengaged from the rod 200 and the spring 201 at the rear side of the machine bearing against the bar 193V of the outerA vframe located at the rear side of the machine, will swing the said frame to its original positiomthereby drawing the saws 184 of the arms 183 out of engagement with the board K and at the saine `time the inner frame actuated by engagement between the arm 204 and the rod 189 will swing the central arms 179 to carry the rearward, saws 130l carried thereby out of engagement with fthe board K. As the wheel .223 is continuously rotated in a clockwise direction` the forward saws 180 on the arms 179 will be swung into engagement with the board J to make the end cuts of the opening 7L whichk `project into the board from the inner face thereof. The angular' bracket 205 will also engage the rod 197 to swing the'outer frame at the front side of the machine inwardly and thereby cause the outer arms 181 to be moved toward the board J to engage the hatchet-like saws 182 with the outer surface of the'board J and thereby make the outer end cuts for the opening h in the board J As the carriage 203 slides toward the rear side ofthe machine, the circular saws 212 will rbe brought into engagement with the two carriages 202 and 203 may be moved longitudinally of the rails 17' to make the longitudinal side cuts of the 'opening 7a. in the board K. After all the cuts in the two boards have boardK and by rotation of the wheel 220 the K been made in this manner, the-carriage 203 will be slid to central position relative to the two boards J and K. Although the move-v ments of the mechanism H are quite complicated to' produce the various cuts for making the openings h in the two .boards lJ .and K,

the two openings may be cuty in the boardsY in very short order by rapid manipulation of the .two wheels 220 and 223, only.

yAfter the vvarious mechanisms have been manipulated as described, the various clamps lB can be released from engagement with the boards, whereupon the boards J and K can be removed from the machine and the material filling the rectangular openings'J of the two boards may be readily knocked out. The l twofboards J and K will then form completed right hand and left hand jambs for a window frame. v

As the mechanisms C and'E arey mounted. on the-carriage 25, it will be seen that these mechanisms can be variably spaced from the right end of the machine by applying a wrench to the head of the shaft39 and thus rotating the shaft to cause the pinion 40 to move over the rack 37. The bracket 36 can also. be slid longitudinally of the` rail .5

v17 and as the gear 92 is mounted on the shaft 87 for sliding movement in the slot 87a of this shaft, it vwill vbe seen that mechanisms 'C and E may beoperated from any position to which they may be slid on the rails 17.

The longitudinal position of the boring mechanism G can also be varied andthe position Y of the brackets 145 within which the shaft 1&6 is mounted, can be varied longitudinally of the rail'17. It is thus possible to adjust 'W the machine for making liambs of various lengths. Numerous other adjustments to vary the length of the openings 'g produced,

and of the rectangularopenings has well as the angular inclination of the grooves c and l may also be made. Different types of saws `may be substituted for the circularand gul-y let saws 57-59 and 58-60, and for the rack sawsA 113 and 114 to producediiferent types y of cuts in the boards worked on. The spacing between the circular sawsy 122 may be varied if desired, or other types of'saws may be substituted for these circular saws. .Al-

though the machine is primarily intended j f chines for mailing the necessary cuts to produce janibs'similar-to the jambs J and K for Window frames and it has been necessary to change the position of the boards Worked on often While the various cuts are being made. with the present machine, the boards need only be once clamped in place and all the necessary cuts may be made in the same for producing the jambs, While they are clamped in lined position., The labor and time saved in producing the jainbs by use of the present machine is great. vWith the present machine, a pair of boards may be clamped in the machine and all the necessary cuts made in the boards to produce finished Window ambs and the boards removed from the machine in less than tvvo minutes.

It will, of course, be understood that various changes may be made in the form, details, arrangement andv proportions of the various parts Without departing from the scope of the prese-nt invention.
